' .ferire Be it lr'nowii that l, Jorim' J. BRENNAN, a Citizen oi: tl 1e U States, residing at Louisville, in the con y or" Jefferson.- aiid State of 5 Kentucky, have invented certain new and useful Improvements in Stills, of which t-lie following is a speeilioatioii.

My invention reates ifo improvements in the means for fontrolliing the passage oi' liqm uid containing solki substances from one eliamlim' io another oi 'the successive vhambers of a still, Willi a View to preventing ifiie` settling of solid substances in suoli marmer as to clog up er -rzlose Llie passages for the liquid.

The invention consists in faire parts and combinations thereof hereinafter set forth and claimed. l

ln order to .maire the invention more clearly understood, have shown iii the accompany4- zo ing drawings means for carrying the same into practical er'ieet without limiting my improvements to the parieular construction which for the sake of illustration l have delineated.

In. said drawings, Figure 1 is a Veriesl seo tional View of so much of' a distilling apparailus as is necessary for the uuderstanoing of my inverilion, the same embodying my improvements a horizontal sectional 3o ori line li of Fig. i.

Referring 'to elle drawings, l iridieases the casing of a siiii of any usual or preferred oonsrruerion. Only a porti-on. 'of suli still is iliustrateri, comprising two of the successive 1; 5 chambers for treating ehe liquid, any desired.

number of which chambers may be embodied in ille still.

At the lower end of each of the discharge-pipes 1s arranged a. receiving or overflow cup 6, which is deep enough to include Vithiri ii' the open- 6G ing 7 of the diseharge-pipe-that is ro when *alle euri is full of liquid all parts oi opening 7' Will be below'il'ie surface of they i1 id, lili-e.arrangeiiienrJ being in title nature-0,1 fluid-trap. The cups araliemisplierioal in 6 5 shape, as shown, lor are substanialiy so, no cause my ser'tling of the soliris in tlieliqifls 'to take place Witliiii a small space at thereuer of the botem oi lie @up and to furnislran inclined Wall 8, leading upward'from suoli 7o center' in a ciirec'iion away @reopening 7 to the iep of lle eur. The cups 6 ,arieattache-fl to the rliapliragiris 2 by rivetiuisoldering, or in any o ther suitable m aimer aiid are arranged ecseiitrieally of the discharge-pipes 77 4, so that said pipes are toward the sigles of the cups and have their deliverr-opeings .v toward the Center and major portions of the oilps, as clearlysliowri in the drawings. Tire hemispherical shape of the @up llas 'the ad (80 Vantage not only ofoausing ille liquid to ioW out rapidly, taking with 1t any sediment or solid matter which might otherwisegcolleo; in 'che cup/[but also has the largest receptive oa pacity with the minimum or Contact upon 85v the separating; perforaecl diaphragm, fleaw.

`iiig die largest possible surface for peiiora`- `tions for the passage of steam or `other#liestiug medium. Each of the diapliragms 2 is formed With a eorisirleraaie miirrberof perf@` 9o rations 9 for the upward passage' .oil sream for other Huid for heating elle liquid in a" known marmer.v l

im their arrangemerir the pipes @are alerwl Hated, the upper pipe being, 'for instance, afi. 95 the left 'hand or; its chamber 3 arid "the neri@ lower 'pipe ai. righi; hand. of its chamber 4, and so saeeessively, this arrangement having advantages, but not being essential 'to these fer pures of i113;improvements,which we are aon-C ed with izlie arrax'igezrxeritfof the dischargeseperiiiig of flie ,pipe )and the shape;

he scilllis' is eorisrruoed according te my improvements the hemisplierieal-sliaped m5; erro prei Uris the clogging of Elie @up yy-rire l ri: ri siispe'risioii in the liquid. 'llie i of a more. or iareral diseharge 1 opening at the lower end of the pipe 4, as by cutting oil' the lower end of the pipe on an angle or otherwise, causes the liquid as it leaves the pipe to swirl against the side of the cup opposite to the opening and loosen and.

.Wash out any solid matter which might otherwise have a tendency to accumulate.

The improved lshape of the cup giving it a small area in contact with the diaphragm, leaves a materiallylarger area for the perforations 9', through which may pass the steam or other heating means, thus promoting the process of distillation in proportion to the size of the still.

What I claim is-.-

1. In a still, the combination With the casing, of perforated diaphragms forming successivechambers, dlscharge-pipes leading from one chamber to another, and receivingcups inclosing the lower ends of the dischargepipes, the `discharge-pipes having lateral openings at their lower ends to cause the washing outl of solid material from the cu s, and the cups having outwardly and upwardly inclined sides facing such lateral openings of the pi es, substantially as set forth.

2; n a still, thc combination of a casing, perforated diaphragms forming successive chambers for the treatment ci? liquid, discharge-pipes leading from one chamber to another, and receiving-eups inclosing the lower ends of the pipes, cach cup having an l l i i I.

adapted to be forced by the stream of disother, a liquid-seal consisting of the combinai tion with a discharge-pipe, of a substartially hemispherical cup arranged to cover the discharge-o iening of the pipes and situated eccentrically of the pipe, substantially as and for the purposes described.

4. In a still, the combination of a casing, diaphragms separating the space within the casing into successive chambers and having means for the passage of steam or'equivalent 'iiuid for the treatment of the liquid, disinclined side, 8, along which solid matter is charge-pipes leading from one chamber to another, said discharge-pipes having lateral discharge-openings, and hemispherical receiving-eups inclosing the lower ends of the said pipes, the cups being arranged ecccn trieally of the pipes with the lateralvdischargevcpeninfrs of the pipes directed toward Itl'iose sides of the cups which are farthest away from the pipes, substantially as set forth.

In testimony whereof l allix my signature in presence of two witnesses. JOHN J, BRENNAN. Witnesses:
